The unprecedented spatial resolution and sensitivity of the Chandra
X-ray Observatory provides a rich archive of serendipitous sources.
The Chandra Multiwavelength Project (ChaMP)
seeks to understand the nature and evolution of
quasars, galaxies, and clusters of galaxies in a large, carefully
constructed multi-wavelength survey. A team of scientists, led
by staff members at the Chandra X-ray Center (CXC) with collaborators
from NOAO, MIT, MMTO, SDSS, UofA, MSU, OSU, Ohio, UT, Rome, Italy and
Bristol, UK, is carrying out a multi-wavelength identification program
for these X-ray sources.

In addition to our extragalactic study, a Chandra Galactic Plane survey,
ChaMPlane,
is being led by Josh Grindlay
